A third grade class has 16 girls and 15 boys a fourth grade class has 18 boys and 15 girls when picking for PE captains will mak

Mkey [24]

Answer:

$\dfrac{90}{341}$

Step-by-step explanation:

3rd grade:

Number of girls = 16

Number of boys = 15

Total number of students = 31

4th grade:

Number of girls = 15

Number of boys = 18

Total number of students = 33

Formula for probability of an event <em>E</em> can be observed as:

$P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}$

Probability of picking a boy from <em>3rd grade</em>, $P_{1} = \dfrac{15}{31} ..... (1)$

Probability of picking a boy from <em>4th grade</em>, $P_{2} = \dfrac{18}{33} ..... (2)$

These are two independent events of picking a boy from 3rd grade and 4th grade.

So, probability the captain chooses 2 boys in the first pick can be found by multiplying (1) and (2) above.

$P = P_{1} \times P_{2}\\\Rightarrow \dfrac{15}{31} \times \dfrac{18}{33}\\\Rightarrow \dfrac{90}{341}$

Vsevolod [243]

Answer: $357 is more amount budgeted for food increase.

Explanation:

Since we have given that

Number of people according to the budget = 150

Cost of food per person= $4.25

Total cost of food is given by

$150\times 4.25=\$637.5$

If the number of guests attending the opening was 56% more than expected,

So, number of guests now is given by

$150\times 0.56=84\\\\150+84=234$

Total cost of food is given by

$234\times 4.25=\$994.5$

Difference between them is given by

$994.5-637.5=\$357$

Hence, $357 is more amount budgeted for food increase.
